As a lifelong knowledge worker--mostly a technical writer, only marginally a software developer, though also, at times, God forgive me, a  Systems Analyst, Media Manager, and (sob!) a Business Analyst --I'd love to know the answer to that one.   

I've been informed by one self-identified "communist revolutionary" that I'm not a "politically unreliable petty-bourgeois intellectual element" but rather a "concerned citizen"--apparently OK with the RCP back in the oughts; and more recently by an even more exalted World's Revolutionary Answer-All Eight Ball that I am a "bullshit worker" who must be eliminated.  

My conclusion: everybody's an asshole.  It's too bad.  Capitalism is headed for the bit-bucket.  Socialism would be such a good idea. 

Actually, I really liked the "concerned citizen" thing, and was heartbroken to learn it's been dialectically transformed of late into a death sentence.  Such are the stern imperatives.

Keep your powder dry.
